Presentation / Conference Contribution
Mehdawi, M. A., Riley, N. G., Ammar, M., Fanan, A., & Zolfaghari, M. (2013, November). Cooperative wideband spectrum sensing with multi-bit hard decision in cognitive radio. Presented at 2013 21st Telecommunications Forum Telfor, TELFOR 2013 - Proceedings of Papers

Cognitive radio offers an increasingly attractive solution to overcome the underutilization problem. A sensor network based cooperative wideband spectrum sensing is proposed in this paper. The purpose of the sensor network is to determine the frequen... Read More about Cooperative wideband spectrum sensing with multi-bit hard decision in cognitive radio.

Comparing historical and current spectrum occupancy measurements in the context of cognitive radio (2012)
Presentation / Conference Contribution
Mehdawi, M., Riley, N., Ammar, M., & Zolfaghari, M. (2012, November). Comparing historical and current spectrum occupancy measurements in the context of cognitive radio. Presented at 2012 20th Telecommunications Forum (TELFOR)

Cognitive radio (CR) technology promises to be one possible solution to solve the problem of lack of frequency spectrum, by allowing access of unlicensed users in licensed bands, based on an opportunistic approach and without interfering with the lic...

Evaluation of a silent speech interface based on magnetic sensing (2010)
Presentation / Conference Contribution
Hofe, R., Ell, S. R., Fagan, M. J., Gilbert, J. M., Green, P. D., Moore, R. K., & Rybchenko, S. I. (2010, September). Evaluation of a silent speech interface based on magnetic sensing. Presented at INTERSPEECH 2010, 11th Annual Conference of the International Speech Communication Association

This paper reports on isolated word recognition experiments using a novel silent speech interface. The interface consist of magnetic pellets that are fixed to relevant speech articulators, and a set of magnetic field sensors that measure changes in t...

A phase modulation-based ultrasonic communication system using Variable Structure Control (2010)
Presentation / Conference Contribution
Ma, S., Wilkinson, A. J., & Paulson, K. S. A phase modulation-based ultrasonic communication system using Variable Structure Control. Presented at 2010 IEEE 12th International Conference on Communication Technology

Narrow bandwidth transducers used in existing ultrasonic data communication systems are known to be devices with a high Q resonant response and low coupling to both the electrical drive and acoustic output interfaces. These features limit the speed o... Read More about A phase modulation-based ultrasonic communication system using Variable Structure Control.

An investigation of the sensitivity of embedded passive component temperatures to PCB structure (2002)
Presentation / Conference Contribution
Stubbs, D. M., Pulko, S. H., & Wilkinson, A. J. An investigation of the sensitivity of embedded passive component temperatures to PCB structure

The embedding of passive components such as resistors, capacitors and inductors within printed circuit boards (PCBs) is motivated, to a large extent, by the desire for increased miniaturization of electronic goods. However, resistors and, to a lesser... Read More about An investigation of the sensitivity of embedded passive component temperatures to PCB structure.

Output feedback sliding mode FTC for a class of nonlinear inter-connected systems
Presentation / Conference Contribution
Patton, R. J., & Huang, Z. Output feedback sliding mode FTC for a class of nonlinear inter-connected systems. Paper presented at IFAC-PapersOnLine

This paper is concerned with the challenge of developing a fault-tolerant control (FTC) scheme for an inter-connected decentralised system in which the individual subsystems are linear but the inter-connections are non-linear functions of the subsyst...
